Improvements in LibreOffice’s PowerPoint presentation support
LibreOffice’s native file format is OpenDocument, a fully open and standardised format that’s great for sharing documents and long-term data storage. Of course, LibreOffice does its best to open files made by other office software as well, even if they’re stored in pseudo-“standards” with cryptic and obfuscated contents. Compatibility with PowerPoint PPT(X) presentations is therefore a challenge, but developers are working hard on improvements…
A few months ago, we announced an initiative to improve the support of PPT and PPTX files in LibreOffice. Lots of great work happened since then and the results are collected below!
Everyone is invited to participate in the PowerPoint support initiative, either in development or testing. If you are interested in joining, please send an email to ilmari.lauhakangas@libreoffice.org.
